Jøtul has produced fireplaces from cast iron since 1853. This is an extremely suitable material that endures high temperatures and rapid changes in temperature. That's why Jøtul chooses cast iron for their fireplaces, just like car manufacturers use cast iron for their engines.
Jøtul's cast iron is recycled scrap iron from local scrap dealers. This is melted down and waste products removed at the same time as carbon and other alloying elements are added. When the melted iron has reached the right temperature, it is analysed in the lab at the Kråkerøy facility and if necessary, extra alloying elements are added to ensure that the cast iron lives up to the famous Jøtul quality. The liquid iron is then poured into moulds of sand to cool down before the cast parts are turned into modern Jøtul wood stoves.
